ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus and a method for automatically adhering tapes, more particularly, to an apparatus and a method capable of automatically adhering a double-faced adhesive tape for splicing papers and a fixing adhesive tape for fixing a tip portion of a stock paper to a side of a stock paper roll to the tip portion of the stock paper in a stock paper wound roll.
2. Description of the Related Art
A stock paper roll including a hollow core around which a continuous stock paper such as a long continuous paper, film, or metal foil or a composite sheet such as a laminated film, etc. is wound has been widely used in various kinds of applications in many industries. For instance, in off-set and rotary letterpress printing machines, a roll body (referred to as a stock paper roll hereinafter) around which a web (referred to as a stock paper hereinafter) to be printed is wound in a rolled manner is loaded on a stock paper feeding device from which the stock paper is fed.
Apart from the stock paper roll currently being fed, the stock paper roll of the same or another kind is loaded on the stock paper feeding device to stand by. When the diameter of the current stock paper roll becomes small, or when the stock paper roll is to be replaced with the stock paper roll of another standard due to an order change, the terminal end of the current stock paper roll and the tip portion of the standby stock paper roll are spliced by a splicer provided on the stock paper feeding device. When paper is spliced by the splicer, double-faced adhesive tape has to be adhered in advance to the tip portion of the stock paper of a new stock paper roll to be spliced. For this reason, a length of double-faced adhesive tape is adhered to the tip portion of the stock paper at the operation site before the stock paper roll is loaded on the stock paper feeding device.
Since the operation for adhering the double-faced adhesive tape to the tip portion of the stock paper roll has been manually conducted up to now, no labor saving has been possible. In addition, when the stock paper roll is transported for loading on the stock paper feeding device, the stock paper may accidentally be drawn out of the stock paper roll unless the tip portion of the stock paper is fixed on the stock paper roll. Therefore, apart from the double-faced adhesive tape for splicing, fixing adhesive tape for fixing the tip portion of the stock paper roll to the side of the stock paper roll is manually adhered to a plurality of positions on the stock paper roll widthwisely spaced apart from each other. Such being the case, the manual operation for adhering the double-faced adhesive tape and the fixing adhesive tape is time-consuming and can interfere with labor saving and automation of the entire production line.
SUMMARY OF THE INVENTION
The present invention was accomplished to eliminate the disadvantages caused by the foregoing problems. The object of the present invention is to provide an apparatus and a method for automatically adhering tapes capable of automating adherence of a double-faced adhesive tape and a fixing adhesive tape to a tip portion of a stock paper of a stock paper wound roll, thereby saving time and labor.
This object is achieved according to the present invention in one aspect thereof by providing an apparatus for automatically adhering tapes, which adheres a double-faced adhesive tape (
10
) to a tip portion (
11
a
) of a stock paper roll (
11
) around which a stock paper is wound and adheres at least one fixing adhesive tape (
12
) so as to bridge the tip portion and the stock paper roll, the apparatus comprising means (A) for transporting the double-faced adhesive tape which includes an endless belt (
15
) transporting the double-faced adhesive tape while at the same time holding the double-faced adhesive tape on its transporting surface, means (B) for feeding the double-faced adhesive tape which feeds the double-faced adhesive tape to the transporting surface of the endless belt while simultaneously stripping a strip paper (
21
) adhered to one face of the double-faced adhesive tape, means (D) for feeding the fixing adhesive tape which cuts a continuous fixing adhesive tape to a predetermined length and adheres the cut fixing adhesive tape by an adhering surface thereof to the double-faced adhesive tape held on the endless belt with a portion of the fixing adhesive tape extending beyond the double-faced adhesive tape, means (C) for cutting the double-faced adhesive tape to a predetermined length, and means (E) for adhering the double-faced adhesive tape and the fixing adhesive tape including posture changeable means (
56
,
67
) which takes a first posture in which the double-faced adhesive tape and the fixing adhesive tape both held on the endless belt are received and a second posture in which the double-faced adhesive tape and the fixing adhesive tape are adhered, the posture changeable means receiving the double-faced adhesive tape and the fixing adhesive tape at the first posture is shifted to take the second posture, whereby the posture changeable means and said stock paper roll are brought close in order for the double-faced adhesive tape to be adhered to the tip portion of the stock paper and in order for the fixing adhesive tape to be adhered to the tip portion of the stock paper and the stock paper roll in a bridging manner.
This object is achieved according to the present invention in another aspect thereof by providing a method for automatically adhering tapes, which adheres a double-faced adhesive tape to a tip portion of a stock paper roll around which a stock paper is wound and adheres at least one fixing adhesive tape to bridge the tip portion and the stock paper roll, the method comprising the steps of conducting and halting the transportation of the double-faced adhesive tape intermittently while sucking and thus holding the double-faced adhesive tape on a transporting surface of an endless belt, cutting the fixing adhesive tape to a predetermined length during a halt of the transportation of the endless belt while facing an adhesive surface of the fixing adhesive tape toward the double-faced adhesive tape held on the endless belt to adhere the fixing adhesive tape to the double-faced adhesive tape in such a way that the fixing adhesive tape extends beyond the double-faced adhesive tape, cutting the double-faced adhesive tape to a predetermined length; and adhering the double-faced adhesive tape to the tip portion of the stock paper while adhering the fixing adhesive tape to the tip portion of the stock paper and the stock paper roll in a bridging manner by receiving and holding the double-faced adhesive tape held on the endless belt and the fixing adhesive tape by a posture changeable means and then changing the posture of the posture changeable means which receives both adhesive tapes while bringing a tape holding surface of the posture changeable means and the stock paper roll close relative to each other.
